Question

For the following overall reation: 2A + B + C ---> products

we can get the following data (in respective order):

[A] mol/L = 0.10, 0.20, 0.20, 0.10, 0.40

[B] mol/L = 0.10, 0.10, 0.20, 0.10, 0.20

[C] mol/L = 0.10, 0.10, 0.10, 0.20, 0.20

Rate = 1.64x10^-3, 3.19x10^-3, 1.28x10^-2, 1.62x10^-3, 2.66x10^-2

What is the order of the reaction with respect to [A] ? [B] ? [C] ?

What is the rate law expression for the above reation?

rate = ?

What is the rate constat from the above data for this reaction?

Let rate = k [A]^x [B]^y [C]^z

1.64x10^-3 =k [.1]^x [.1]^y [.1]^z..................................1

3.19x10^-3 =k[.2]^x [.1]^y [.1]^z..................................2

1.28x10^-2 =k[.2]^x [.2]^y [.1]^z...................................3

1.62x10^-3 =k[.1]^x [.1]^y [.2]^z..................................4

2.66x10^-2 =k.[.4]^x [.2]^y [.2]^z..................................5

debide 1 and 2

1.95 = 2^x

x=order with respect to A = 0.95 =1

devide 2 and 3

2.49 =1/2^y

2^y = 1/2.49

y = order with respect to B = -1.31

devide 1 and 4

1.01 = 1/2^z

2^z=1/1.01

z = order with respect to C = 0

Rate = k*[A]^1[B]^(-1.31)

from 1

k= 33.48*10^(-3)
